What is Osteoarthritis?

Osteoarthritis, the most common type of arthritis, is a condition that affects the joints in your body. It happens when the cartilage, the smooth, protective tissue covering the ends of bones in joints, wears down over time. This causes the bones to rub against each other, leading to pain, stiffness, and reduced movement.

Cartilage acts like a cushion in a healthy joint and allows bones to glide smoothly past each other. However, this cartilage breaks down in osteoarthritis, making joint movement more difficult and painful. The condition can affect any joint, but it most commonly occurs in the hands, knees, hips, and spine.

Osteoarthritis develops slowly over time and can worsen with age. It's not just a problem of wear and tear, as previously thought. Instead, it affects the entire joint, including bones, cartilage, ligaments, fat, and the tissues lining the joint (called the synovium). Common symptoms of osteoarthritis include:

  • Pain in the affected joints, especially during or after movement

  • Stiffness, particularly in the morning or after periods of inactivity

  • Tenderness when pressure is applied to the joint

  • Loss of flexibility and reduced range of motion

  • A grating sensation or crackling sound when using the joint

  • Swelling around the affected area

  • Formation of bone spurs (extra bits of bone) around the joint

The exact cause of osteoarthritis isn't fully understood, but several factors can increase your risk of developing it. These include:

  • Age (it's more common in older adults)

  • Being overweight or obese

  • Joint injuries or overuse

  • Genetics (it can run in families)

  • Certain occupations that put stress on particular joints

  • Other forms of arthritis, like rheumatoid arthritis

While there's no cure for osteoarthritis, various treatments can help manage symptoms and improve quality of life. These may include:

  • Pain relief medications

  • Physical therapy and exercise

  • Weight loss (if overweight)

  • Assistive devices like canes or walkers

  • Hot and cold therapy

  • Joint replacement surgery (in severe cases)

Trend

  • In the United States, osteoarthritis affects over 32.5 million adults. This number has likely increased over the past five years due to an aging population and rising obesity rates.

  • While exact projections for the next five years aren't available, the trend suggests that the number of people affected by osteoarthritis will continue to grow as the population ages.

History

Osteoarthritis has been around for a very long time. Evidence of the condition has been found in the skeletal remains of people who lived thousands of years ago. However, our understanding of osteoarthritis has changed significantly over time. In the past, it was viewed as a result of wear and tear on joints as people aged. Now, we know it's a complex disease involving the entire joint and can be influenced by various factors beyond aging. This shift in understanding has led to new approaches to treating and managing the condition, focusing on pain relief, preserving joint function and improving overall quality of life.
